.' NORMAN @ur inventionv relates' to improvements in ventiiator outtake finest. and' the object of our. improvement is to supply' for: use in housings for 'hogs or.` other animals, a deff vice ofthis class-Awhich-is'f efficient. in `the discharge of; foul air., and which is collapsible to provide head room in a passage, be`

side b'eing so d'etachably 'suspended' as to rendenit possible to swing' .the depending ytine away' from `the vertical.

l' Having described ourinvention, whatwev claim as new, 'and desire lto secure by'Letters Patent,'is,: Y

1. A device of the class described, comv prising in combination, a vertically disposed lventilator outtake flueyand a. plurality. of

flexible means detachably connecting opposite partsoftheupper end of the fluer in communication with a roof opening for free 4swinging displacements of the flue when cei' Vanother section having an outwardly projecting bend above saidv crimp within the firstymentioned section to be supported upon said -crimplin onevposition, means for releasably vsecuring the lower of the sections `when telescop ed,.aiid flexible members attached to the upper section of the flue anddetachably con'- nected vto avroof therea-bovev to swingingly suspend the tube in communication with a roof opening thereabove.

v y3. A device of the class described, comprising in combination,l a vVentilating cupola mounted in a roof aperture,- a vertically disposed Vventilatorouttake, tube composed ofVv telescopically connected sections detacli'ably flexibly suspended for' free swinging below and in communication with said cupola, oney section having an inwardly projecting stop part, ain'dvanother sectionfslidable within said sectionhaving an outwardly projecting stop part to engage the stop' on! zthe first-men# tioned' section when the second-mentioned section is withdrawn to engage said'parts, means yfor releasably securing the lowermost section in a telescoped condition, and a rock able imperforate damperv'in the lowermost section mounted frictionally therein.

4t. A-k device of the class described, comprising in combination with va.. Ventilating cupola having a rectangular base part mount-n ed in a rectangular opening of the roof of a building.,l ot an open end tube suspended from places spaced from the upper end thereof by pairs of oppositely locatedv fleX- ible membersv detachably. hung from said roof, to normally hang vertically therefrom, the upper end part of the tube above the connections to said members being shaped with an enlarged rectangular head to fit loosely within the rectangular base part ofthe cu* pola, whereby when a pair of said flexible members are detached on oneside, the tube willswing to the other side by the influence of gravity. j
